You can change the shutter speed and aperture value by turning the front and rear dials in the “P” (Program AE) mode. In order to avoid blurred images (due to shaking while releasing the shutter), or to open the aperture, change to “PH” (high speed). For slower shutter speeds and wider depth of field, change to “PL” (low speed). This function allows you to make these changes quickly.
